refactor: split auto_handle_wsol into create/close_wsol_ata params

- Replace auto_handle_wsol with create_wsol_ata and close_wsol_ata
- Enable fine-grained control over wSOL account lifecycle
- Update all trading protocols and documentation
- Add open_seed_optimize support in fast functions

This provides better flexibility for batch operations and advanced trading.
